  • A Study on Bituminous Coal Base Acid Ratio to the Slagging

    Apr 27, 2021 · This study found correlation between high furnace rear path temperature (FRPT) that is observed to be above 800℃, with the build up of ash accumulation inside the boiler, for the studied coal. Thus, a high base acid ratio causes the accumulation of coal ash, thus reducing the heat transfer process which results in high FRPT of the boiler.Learn More
